A circuit employing an array of reconfigurable processing elements for wireless baseband processing. The circuit includes a first linear array of reconfigurable processing elements for processing signals from a first channel, and a second linear array of reconfigurable processing elements, coupled in parallel with the first linear array of reconfigurable processing elements, for processing signals from a second channel that is concurrent with the first channel. The circuit also includes a frame buffer array having a number of frame buffers that corresponds to a number of reconfigurable processing elements in the first and second linear arrays of processing elements. A point-to-point data bus is connected between each reconfigurable processor and an associated frame buffer. A shared data bus is connected between the first and second linear arrays of reconfigurable processing elements and the frame buffer array.
